LIFTING DEVICE.

Specification of Letters Patent.

-Patcnted Nov. 211, 1915i.

Application filed March 28, 1916. Serial N0. 87,363.

To all "whom it may concern Be it known that I, SAMUEL H. 0mm, :1native-born citizen of the United States, residing at Lodgepole, in thecounty of Cheyenne and State of Nebraska, have invented new and usefulImprovements in Lifting Devices, of which the following is aspecification.

This invention provides a device for extracting pump rods and pipes fromwells, and aims to produce a construction by means of which both thepipe and rods can be simultaneously or independently elevated, and thesection or sections of these parts subsequently uncoupled withoutnecessitating the removal of the device from the block and tackle hook,and also eliminating tangling of the rope.

The nature and advantages of the invention will be better understoodfrom the following description when taken in connection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawing forming part of this specification like numerals ofreference indicate similar parts in the several views and wherein Figure1 is a longitudinal sectional view showing the device in use. Fig. 2 isa sectional view taken on line 22 of Fig. 1.

Referring more particularly to the drawing A indicates the pipe made upof a plurality of detachably connected sections, and B the pump rod orlike tool desired to be removed.

The device forming the subject matter of the present invention consistsof a hollow tubular member 10 which may be of any suitable length, andhaving arranged therein a bracket 11 which latter preferably includesspaced parallel bars 12, and sockets 13 at the opposite ends of thebrackets at which point the said bars are integrally connected. Thetubular member 10 adjacent its upper and lower extremities is providedwith diametrically opposed alined openings 14% adapted to receive aheaded bolt 15 which passes between the spaced bars of the bracketprovided to limit the adjustment of the bracket within the tubularmember in both directions, and also serving to hold the tubular memberand bracket operatively associated. Arranged at the upper end of thebracket is an eye bolt 16 swiveled within the socket 13, while thelowermost socket of the bracket is interiorly threaded to receive theexteriorly threaded end of the rod 17. This rod projects an appreciabledistance below the tubular member 10, and is exteriorly threaded forassociationwith the pump rod or 1qther tool desired to be removed fromthe we In practice the device is supported in vertical position by meansof a block and tackle not shown, the hook of which is engaged with theeye bolt 16. The device is then lowered into proper position to permitthe lower end of the rod 17 to be coupled with the adjacent end of thepump rod, while the lower extremity of the tubular member 10 isexteriorly threaded for a similar association with the adjacent end ofthe pipe. lVith these parts connected, it is manifest that both the pumprods and pipe may be elevated the requisite distance to permit one ormore sections of the pipe or pump rod to be uncoupled from the remainingportion of their length. By reason of the fact that the eye bolt 16 hasa swivel connection with the bracket, it is obvious that subsequent tothe elevation of the pipe and pump, these parts can be rotated in theproper direction together with the tubular member 10 and rod 17 for thepurpose of uncoupling the desired number of sections of the pipe andpump rod, without the tackle rope being twisted or tangled or in any wayinterfering with this operation. When the parts have been uncoupled,they can be easily and quickly lowered to the ground with safety, andwhen rested upon the ground the tackle rope being slack permits thesection or sections of the pipe and pump rod to be uncou pled from thedevice, It is of course understood that the tubular member 10 and rod 17can be used in combination as hereinabove stated, but when it is desiredonly to elevate the pipe the rod 17 can be dispensed with as it isdetachably associated with the bracket.

It is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent without requiring amore extended explanation and therefore the same has been omitted.However I desire to have it understood that I do not limit myself to theprecise construction illustrated, and that various changes may be madewhen desired as fall within the scope of What is claimed.

hat is claimed is 5 A device of the class described comprising a hollowtubular member exteriorly threaded at one end, a bracket arranged withinsaid member, means for holding the parts operatively associated, an eyebolt 10 swiveled to the upper end of said bracket,

and a threaded rod depending from the op posite end of said bracket anddetachably connected therewith.

In testimony whereof I aiiix my signature in presence of two witnesses.
